PERM UTATlON-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 490,784, dated anuary31, 1893. Application filed July 11, 1892- v fierial No. 439.629. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOSIAH J. DEAL, a citizen of the United States, anda resident of Canton, county of Stark, State of Ohio, have invented anew and useful Improvement in Commutation-Padlocks, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, making part of this specification.

My invention relates to an improvement in commutation padlocks, andconsists in providing a lock of tubular form havinga series of tumblersthat rotate about a central shaft transverse the tubular case, to lockthe shackle within the case.

With these ends in view, my invention relates to certain features ofconstruction and combination of parts as will be hereinafter describedand pointed out in the claims.

Figure 1 of the accompanying drawings is a perspective of a padlockrepresenting my invention having a portion of the case cut away to showthe tumblers and locking pins in unlocked position. Fig. 2 alongitudinal section partly in perspective. Fig. 3 is a view partlyperspective and partly sectional showing the tumblers partly withdrawnfrom the case. Fig. 4: a perspective of one of the tumblers and: Fig. 5a similar view of a spring to hold the tumblers in desired position.Fig. 6 is a detailed perspective.

Similar letters of reference indicate corresponding parts inall of thefigures of the drawings.

The object sought by the construction hereinafter described, is toprovide a lock structure of a keyless tumbler form adapted for a rangeof sizes of lock, varying from one fourth of an inch in diameter and onehalf in length to the size shown by the drawings, or larger if desired.

Referring to Fig. 2, A represents the inclosing case which is ofcylinder or tubular form, in which are fitted two heads B and O, theformer supportingashaft D, on which are loosely mounted the lockingtumblers E, F and G,

x the other end of the shaft is passed into a central aperture to in thehead 0 and secured by a pin b. The shackle H has one of its endspivotally secured in a recess 0 provided in the head 0, the other orfree end adapted to pass into a similar recess 01, diametricallyopposite erator may be directed in operating the lock,

the inner end of the bolt to pass into an aperture in the head whichassists in retaining the shackle in the head when closed in the case.

On the shaft D are placed the tumblers E, F and G, each of which isprovided with the usual turn pin f and is operated in the usual way; toturn the tumblers to bring the. peripheral notches h to register onewith the other, to allow the tumblers to pass the locking pins It asshown in Fig. 3. the tumblers are spaced apart by the hub or washer Z.On the under side or inside of the head O is provided any desired numberof perforations to receive the pin fin tumbler G, by which thecombination of numbers or letters on which the parts are locked may bechanged. There is also provided in the periphery of the head B, a groovem through which the pinsk may pass to permit the tumblers and heads tobe drawn from case. The pin fpassing through the tumbler Or, one end ofwhich will enter an aperture on the head 0, the other to engage thepinfin the tumbler F. The tumblers E and F are diametrically smallerthan the head B and case to provide space for the springK which servesas a brake on the tumblers E and F. The

spring or brake K is held in position, or against rotation by the screwL and pins k. To regulate the longitudinal movement of the tumblers andheads, screw L is provided which projects into the case to limit thelongitudinal movement of the locking parts in the case, it passing intothe slot 19 in the springK, and engaging the head B, and to remove theparts from the case the screw must be turned back to allow the head B topass. The shoulders on the shackle will engage or strike the end of thecase to stop the inward movement.

To operate the lock, the shackle is held either by the staple throughwhich it is passed, or by the fingers, the case turned back and forth towork out the combination which has been previously arranged and isunderstood too by the operator, to bring the slots h h and h in line asshown in Fig. 3, when the head 0 may be drawn out of the case to releasethe shackle. To lock the shackle in the case, return the free end intothe head 0, press the head into and turn the case to distribute thetumblers.

Having thus described the nature and object of my invention, what Iclaim and desire to secure by Letters Patent is:

1. The combination in a commutation padlock of a cylindrical case whosediameter is less than the length thereof, of a series of locking pinsarranged longitudinally and projecting therein, and the tumblers havingengaging pins, and peripheral grooves, substan tially as described andfor the purpose set forth.

2. The combination with the tubular inclosing case, having inwardlyprojected locking pins and a stop screw, of the sliding heads B and O,the tumblers interjacent the heads to rotate transverse the tubularcase, and the spring brake K to embrace the tumblers h and h to holdthem in desired position, substantially as described and for the purposeset forth.

3. The combination in a commutation lock of the tubular case, havinginwardly projected locking pins and perforations e, of the head 13,having secured therein a shaft projected therefrom through the case,tumblers to m: tate on said shaft transverse the case, the head 0,shackle H and spring bolt J, substantially as described and for thepurpose set forth.

In testimony whereof I have hereunto set my hand this 2d day of July, A.D. 1892.

JOSIAH J. DEAL.
